When Yinreng talked about his interest, he had ten thousand reasons to say it to convince others. The little mouth was too loud, Kangxi could not bear it, and Yinzhi could not bear it.

After about an hour, Yinzhi asked him: "Are you tired?"

Yinreng shook his head.

"Then are you hungry? Is it hungry anyway?"

Yinzhi said angrily: "Look at the sky, you have been holding me for so long. What's the use of persuading me? You can tell these words to Khan Ama, and it's more useful to say to the courtiers than to me."

"I'm not trying to ask my elder brother for advice," Yinreng said embarrassedly: "Now the only one who can trust me is the elder brother."

If you look for Khan, Ama will be beaten, and if you look for Azhen, you will be pecked by a goose. Others can’t give him any advice. If you can talk to him, the only one who is the partner he talks to is the eldest brother!

Yinzhi said that he was in a good mood when he gave him a straight shot, especially the feeling of being trusted and needed, which made him feel that he was the only object of trust that his younger brother relied on and trusted.

Thinking of this, Yinzhen was in a good mood and asked someone to prepare a midnight snack for Yinreng.

The kitchen brought them a walnut and almond dew, which tasted sweet and bitter, and it looked pretty good.

After sleeping for a night without a dream until dawn, Yinreng woke up from the house that the prince had packed out and touched his head mutteredly: "I was going to write a memorial for Khan Ama last night! I fell asleep without writing it."

He seriously suspected that he had been knocked at by Brother Tutu!

Yinzhi met Yinreng when he woke up. He didn't have to go to court meetings. He was practicing in the courtyard at this time.

Those fists were so full of vigor that they looked a bit fancy at first glance. Perhaps because they were getting taller recently, Yinzhi's appetite was much bigger than before, and he specialized in picking meat to eat.

The two brothers had a meal early in the morning. They ordered a chicken porridge, but they didn't think it was enough, so they ate meat buns.

When he was alone, Yinreng couldn't eat so much, but seeing that Yinzhi had a good appetite, he unknowingly ate very full.

During the meal, Yinreng looked at Yinzhi at all times, his eyes full of suspicion.

Yinzhi looked upright and innocent. Didn’t he just drink an extra bowl of calming the gods? Drinking it is good for the health, or is it a prescription prescribed by the hospital to improve sleep and nourish the brain. He also drank it yesterday.

After Kangxi sent him to ask Yinreng to go to court, Yinzhi returned to his house and wrote a few pages of big words before going to the study.

He went to the study to attend class first, and then went to the Ministry of War after the court meeting.

Yinreng failed to understand the details of the eight-legged essay in the Qing Dynasty before the court meeting, and did not have time to sort out his ideas and write the memorials, so it was really inconvenient to mention this matter.

After the court meeting, it is time to teach my younger brothers again today. Yinreng does not need to go to the Ministry of Rites to click Mao on the teaching day. He teaches once every five days, and the frequency is not high.

When Yinreng arrived at the study room, Yinzhi and Yinzhen were already waiting for him in the hall.

Seeing his younger brothers as tender and cute as green, Yinreng's mood suddenly improved.

Today he is going to teach chemistry to his younger brothers. Others may not know what chemistry is, but Yinreng hopes that these two younger brothers who have been trained by him since childhood can understand him better than anyone else and understand the richness and diversity of this world.

"If you don't learn new knowledge and accept foreign information, you will be like a frog in the well, only seeing the inch of the sky at the wellhead."

Yinreng said: "The science of chemistry is one of the things to study. Previously, Gu Youyou taught you two the concept of chemical reactions. Today Gu Yi brought learning experimental supplies."

His experimental supplies include beakers, measuring spoons, measuring cups, funnels, mixing rods, test tubes, etc., using the best technology of the official glass kiln, they fired pure transparent glass without impurities. The measurements are also drawn on them. Just looking at the things in these bottles and jars, it looks extremely frightening.

Yinreng did several simple experiments, such as using starch to expand in contact with water, and doing neutralization tests, using acid and alkali to show the color change of the flower juice. Then he put a complete set of equipment in front of his younger brothers and demonstrated to them how to operate it and do the experiment in a safe manner.

"Calculating limestone with high temperature can get quicklime."

"Calcium hydroxide is obtained after soluble in water."

"These white powders are very useful and can be used as building materials, improve soil, etc.."

"When doing this experiment, a large amount of carbon dioxide will be released, which can make the clarified lime water turbid."

Yinreng's course was like a magic trick. Yinzhi was stunned and Yinzhen's eyes were straightened.

Yinreng himself studied with Xiaomei's courses since he was a child, and he had a strong ability to accept it. Yinzhi was young, confused and confused. He could only barely reach the state of "knowing the truth, not knowing why".

Compared to Yinzhi's lack of understanding, Yinzhi was particularly affected!

"Did you all remember the experimental steps?"

Yinreng asked with a smile.

Yinzhi nodded: "Remember 80%."

It would be too easy to remember these experimental steps with Yinzhen's memory.

Although he still couldn't understand the profound principles that Yinreng said in his heart, Yinzhen thought confidently: It should be no problem to do it.

Seeing this, Yinreng brought an alcohol lamp for Yinzhen and stuffed an experimental match into his hand.

Yinzhen was stiff and immediately didn't know where to put his hand.

“Look the alcohol lamp.”

Yinreng reminded Yinzhen with a gentle voice, and saw the fourth brother sliding the match carefully, and the small firewood immediately burned, illuminating his fingertips.

"Have you ever played the hot memorial?" Yinreng was very curious.

The fire slicing thing has been available since the Song Dynasty! A man named Tao Yi in the Song Dynasty recorded the thing called "Huocun", which was the childish shape of the earliest matches. Yinreng made it just to improve the appearance of the fire slicing and use wood that is easier to burn.

In the following steps, Yinzhen was in a hurry and told Yinreng with practical actions, what it means to "learn and lose one's own way."

Yinreng touched his fourth brother lovingly and sighed, "It's okay if you can't learn it. Even if you don't want to understand it very much, if you have an orphanage, your fourth brother's knowledge will be much more broad than that of ordinary people, and it won't be considered in vain."

Yinreng shook his head: Hey, the fourth brother is stupid, and at this time he can only look at the talent of the third brother.

When Yinzhen saw his little look, he knew what he was thinking, and he suddenly felt a little unhappy: I am stupid? If I am stupid, can I be the emperor for more than ten years and smooth out the mess left by Khan Ama one by one?!

It’s one thing to pretend to be stupid, but it’s another feeling to underestimate Yinreng.

On the other hand, Yinzhi's memory gradually strengthened under the study and tried it a few more times, and then he roughly recorded the experimental steps. When Yinreng asked him questions again, he could answer most of his questions.

When teaching the new courses of his younger brothers, Yinreng tried to arrange some content that could easily arouse their interest to teach, and focused on interaction and communication.

Among several courses, they can understand physics classes faster, followed by biology, followed by chemistry, and the worst is mathematics.

There are also teachers in the study room who teach the princes how to use mathematics, but the mathematics taught by the teacher is much simpler, and they do not teach them what "geometry" is.

Nothing was hidden from Kangxi when Yinreng taught his younger brothers. The emperor showed a strong interest in "geometric mathematics" and "physics". Yinreng was obviously not a gentleman who could educate the emperor, nor could he satisfy Kangxi's desire for knowledge, so the emperor simply summoned the missionaries to come to the imperial court to explain to him.

The teaching time was almost over. Yinreng asked his younger brothers to review what they had learned today, and asked Yinzhi and Yinzhen to exchange notes to check for each other's omissions.

And he himself took out paper and pen and wrote quickly to write the memorial that he planned to write to Khan Ama.

He thought hard for a long time and discussed the benefits of abolishing the eight-legged essays from all aspects and the harm of retaining the eight-legged essays to do the questions. When he was immersed in writing, he could not feel the movement around him.

Yinreng heard a crisp sound.

"Even if the eight-part essays are abolished, there is no way to replace the eight-part essays to obtain scholars."

He raised his head in surprise and saw Yinzhen standing beside him, holding the newly written notes in his hand, tilting his head and peeking at what he wrote.

Yinreng let him see it openly, but today's fourth brother seems to be different from usual?

He hesitated and said, "Why did the fourth brother say that?"

Yinzhen's eyes were calm, and he did not have the innocent light as bright as Yinzhi, but he was deep like an older person.

He said: "The benefits of eight-legged essays outweigh the disadvantages. If the second brother does not want to come up with a method that is better than eight-legged essay style, he will not be able to convince Khan Ama."

Yinreng felt that his fourth brother was very mature and seemed to have become much smarter, so he couldn't help but take a look at him.

Yinzhen let him look at it, and his heart was cold: Did the prince find out?

Then he thought: What can he do if he finds it?

Yinzhen suddenly felt relieved: This life's crown prince is different from his previous life, and he is even more extraordinary than what I have shown.

Anyway, this difference should be something Khan Ama should worry about. What does it have to do with me?

There was a prince with pearls and jade in front, and Yinzhen followed behind him, standing in the shadow of the prince's light, comfortable and safe.

Yinreng looked down at his article and said in a loss: "Brother said the same thing. The fourth brother is smart and I thought of going to the same place with my elder brother."

He also knew that the eight-legged scholars could be passed down to this day, and he must have its advantages. From the perspective of the crown prince, he could roughly infer that it was conducive to "stability", various aspects, whether it was the temperature of examination norms or the stability of the Qing Dynasty ruled the world.

"But what you said is more beneficial than disadvantages, but I will not recognize it." Yinreng did not regard Yinzhen as a child, but as an object of communication like Yinzhi. "This is clearly a matter of harm than advantages. Its suppression has violated the original intention of the initial establishment of the eight-legged essay to recruit scholars. Now it is no longer the previous dynasty. As the disadvantages gradually emerge, what we need to think about should be how to find a better way and how to change it, rather than a road to the dark, knowing that there is a dead end ahead, but still do not want to change. If a person walks the wrong path to the end, it will be a doom for a person. If a country walks the wrong path to the ground, it will become a doom for a million people."

Yinzhen frowned. He actually saw the keenness from the nine-year-old prince?!

His eyebrows and eyes are tender, but his sharpness is first revealed. This child is no longer the naughty guy who was laughing and always thought about playing around without hesitation.

Yinzhi looked around and didn't understand what they were saying, looking beyond their condition.

This is what a six-year-old child should look like. Yinzhen is younger than him, but he has already spoken clearly and organizedly. Judging from his words and deeds, he is obviously not a stupid person, and he is even very likely to be a genius.

Yinreng's heart trembled with his fourth brother's head tilted his head, and he wanted to squeeze his chubby cheeks again.

Yinreng didn't feel the strangeness in his fourth brother's body. He glanced at Xiaomei quietly.

The system covered his tiger's head and whined.

[Xiaomei doesn't know anything, Xiaomei can't say...]

Yinreng: OK, if you don’t say it, I won’t say it. If I do this, I’m afraid there will be another adventure. Does he have a little beauty in him?

[Xiaomei is a big friend! She is unique!]

The white tiger loudly refuted Yinreng's guess, and the tiger's eyes burst into tears.

Yinreng knew it and no longer asked Xiaomei, but observed Yinzhen, who seemed to be wise and foolish.
